TINY PACKAGE HIGH EFFICIENCY STEP-UP DC/DC CONVERTER - Introduction The AM9108/9 is a CMOS step-up switching DC/DC converter that mainly consists of a reference voltage source, an oscillator, and a parator. The G908/9 allows the duty ratio to be automatically switched according to the load (light load: 50%, high output current: 75%), enabling products with a low ripple over a wide range, high efficiency, and high output current. With the G908/9, a step-up switching DC/DC converter can be configured by using an external coil, capacitor, diode and NMOS or NPN. The built-in MOSFET is turned off by a protection circuit when the voltage at the LX pin exceeds the limit to prevent it from...
